A Sharper Scaling is a high quality image scaling technology mainly developed for upscaling. An implementation for Microsoft Windows is available as freeware from this site. The following examples are most clear if the images are viewed in their original resolution. Otherwise, the browser does another image scaling on top, somewhat obfuscating the differences these examples are about. It's usually easy to get the original resolution shown.

On a Windows PC or Notebook, just hold down the Ctrl key and spin the mouse wheel up or down until the left side pattern of this test stripe looks exactly like a miniature version of the right side pattern chessboard-like.

For comparison, all examples show the results of two conventional methods as well. Bicubic interpolation is what most image editors offer as the most appropriate method for image scaling. The interpolation results are a bit blurry, so another conventional action might be to sharpen them. The sharpening method used for the examples is "unsharp masking". I suppose it's also based on bicubic interpolation internally, but I may be wrong.

The function has a single adjustment "Reduce Noise" which was set to zero for the test because the pictures have very little noise only.

Small versions of whole pictures are probably not the most typical use case for image upscaling. Ideally, upscaling is the first geometric transformation, which means that the input still has the resolution of the camera.

The next examples are details of pictures coming directly from the cam:. These are critical details not random. Many other details don't show much difference between A. Although A Sharper Scaling does nothing but scaling images, it can also contribute to the quality of other geometric transformations like rotation, perspective correction, or lens distortion correction. Just upscale the image by a factor of x before the transformation and downscale it back by x after that.

Whether this has a benefit or not depends on the image editor used and the type of transformation. In the example, x was chosen to be 2. The image editor used was Adobe Photoshop CC Alternatively available: Mobile zipped versionno installation required. See: legal disclosure. The tool has limitations in this regard because of the limited 32 bit address space.

It's a complex combined limitation involving all parameters. For many use cases, that limitation should be far from being a problem. The alpha channel of the source image is ignored. Output is always without alpha channel.

Processing speed improved.Select File. Using the latest Deep Convolutional Neural Networks. It intelligently reduces noise and serration in images to enlarge them without losing quality. See demo images. With other software such as PS, enlarged images still look fuzzy, and have visible blur and noise.

Colors are well kept, and almost no gitter or doubling is visible. More importantly, the noise, which seriously influences quality, cannot be seen in result images. Anime images and illustrations are nearly perfectly processed, colors, details and edges are all well kept.

Regular photos are supported as well. Estimated remaining time will be showed once the process starts. The actual processing time is usually shorter than that estimated.

I'm developing a pixel art 2D platformer for PC and smartphone, but I'm stuck on a technical issue.

RESOLUTION ≠ DIMENSIONS in Photoshop!

I chose to have a 32x32 tile resolution, and a 64x64 character sprite resolution. The levels are divided in to sections that I call "screens", and in each screen I've got 40x In the game, I have got a double-jump mechanic, so I need to have a good vertical view range on each "screen". Here comes the issue: x is not a very high resolution. On HD monitors the window would be not be big, and if I upscale the resolution by 2x, it will be in x and the window would be much larger than an actual HD monitor.

If I try sizes in between x and x the graphics start to stutter, or are deformed. How can I solve this issue? Is there a solution that does not require me to redraw all the tiles and the sprites in 16x16 format? For anyone wondering why this is an issue for pixel art, here's a quick example using a scene from Super Mario World:.

If we just scale a pixel art game from to at runtime the way a typical game camera mightwe get artifacts because of the non-integer ratio of screen pixels per source texel.

Check out the inconsistency in the numbers from the scaled example on the right, and how garbled the leaf and Mario's ear look. It's playable, but it's lost that charming pixel art crispness. And in motion these artifacts can crawl across a spritemaking it look shimmery. Using a filtering mode that blends adjacent pixels will avoid the ripples, but smear and blur the pixel art instead, so it's also not very desirable. As you note, scaling 1x is too small and 2x is too big, by just as wide a margin both ways, and there's no whole-numbered scaling ratio in between for us to choose.

You may be able to extend the cropping, showing more of your scene at a time on high-res screens. This too can affect how the game plays, eg. You may by able to compensate for this with camera logic, having the view pan to follow or anticipate the player, so the important content is still visible in one screen at the smaller crop, but there's no universal best camera to use. If you decide to go this route, try sharing some details of your gameplay and current camera, and an example scene.The algorithm identifies pixel-level details to accurately shade the new image — but more importantly, the algorithm can create smooth, curved contour lines from only-connected-on-the-diagonal single pixels.

Look at the Super Mario World dolphin below, and compare it to the original source sprite below that: the results speak for themselves. To achieve such beautiful images, the researchers use a complex blend of pixel analysis and spline curves. These approaches in specific, and vectorization of bitmaps in general, are nothing new — Adobe Illustrator does it quite well — but in this case, because the researchers were only working with 8-bit pixel art, they could create a very specialized algorithm.

Finally, these pixel cells groups are re-shaped, smoothed with spline curves, and then rendered as edges or shaded areas.

For a better idea of just how accurate their algorithm is, you should look at the other nearly all Nintendo-related samples in the Depixelizing Pixel Art research paper.

For example, are Space Invaders really meant to be cute and round? At long last, we might be able to play Super Mario Bros. Read more at Depixelizing Pixel Art. This site may earn affiliate commissions from the links on this page. Terms of use.

An image file format may store data in uncompressed, compressed, or vector formats. A raster graphics image is a dot matrix data structure, representing a generally rectangular grid of pixels, or points of color.

Useful when you need to reduce GIF size or fit the image in specific dimensions. GIF animation resizing is sometimes tricky, and you will probably have to choose between a smaller file size or image quality. Some gifs may need the "coalesce" option which removes all optimizations from frames if other methods fail and output image is flickering or has strange artifacts, but it may significantly increase file size and is very slow.

Try different resize methods if you are not satisfied with the result. Gifsicle is usually the fastest tool and produces smaller files, but is designed for speed, not quality. You can select the action to perform if the aspect ratio of the source image and your chosen size does not match - center and crop the image, stretch the image to fit, or force the original aspect ratio.
